Adult.--Very much like Iole gularis, but chin and throat light
drab-brown; whitish shaft-streaks less conspicuous than in either
I. gularis or I. guimarasensis; sides of breast and flanks grayer;
under parts with fewer streaks of pale yellow. Ten males measure: Wing,
102 to 107 (105); tail, 90 to 99 (95); exposed culmen, 21 to 24 (23);

"Quite common in Mindoro. Two males average: Length, 222; wing,
100.5; tail, 91; culmen, 26; tarsus, 19; middle toe with claw, 22. A
female, length, 235; wing, 97; tail, 90; culmen, 27; tarsus, 18.5;
middle toe with claw, 21. Iris chocolate-brown; bill, legs, feet,
and nails leaden." (Bourns and Worcester MS.)
On April 2, 1905, I collected, in Mindoro, a nest with three
eggs of this species. The ground-color of the eggs is white, under
shell-markings faint lavender, and entire surface thickly and uniformly
marked with elongated and twisted spots of reddish brown. The eggs
measure: 26.1 by 18.2, 25.4 by 18, and 25.1 by 19.
The nest was composed of several leaves which were held in place by
threads of a black hair-like fungus; cobweb and green moss in small
quantities also entered into the construction. The lining consisted
of a quantity of long slender fibers.
